► A continuous wavelet transform was used on single trial EEG recordings. ► A theta (4–8Hz) waveform was constructed from the wavelet coefficients. ► Comparisons in error processing were made between PTSD and control subjects. ► Measures from the PTSD subjects were deficient when compared to that of...
